如何使文件只发送一次不重复？ Function App 和 blob 存储容器

Question

我有这个功能的应用程序，当我把一个文件放在blob存储容器上时，我得到了一次文件！当我放置 2 个文件时，我的电子邮件收件人收到 4 个文件，同一个文件两次！当我放 3 个文件时我得到 9 个文件，同一个文件重复 3 次，当我放 4 个文件时我得到 16 个文件和同一个文件重复 4 次，如何解决这个问题？

这是我的函数应用程序：

Answer 1

由于 Send an email (V2) 连接器用于 Lists blob value 的每个循环，您将收到一式两份的所有内容，因为它遍历了您设置的 folder/container。从我们的终端复制后，当我们将 Get Blob 的 Blob 路径更改为 When a blob is added or modified (properties only) (V2) 的 List of Files Path 并且也在 Send email 中使用 When a blob is added or modified (properties only) (V2) 内容时，它正在工作，我们可以收到电子邮件当前项目一次。

这是我的逻辑应用程序的架构
